Evaluating pXRF instrument performance using reference materials

The portable X-Ray Fluorescence (pXRF) instrument provides fast, real-time, non-destructive, multi-element geochemical data (i.e. elemental concentrations) on rocks and minerals at a relatively low cost and with minimal sample preparation. This study quantifies the precision and accuracy of measurements collected by the WGNHS pXRF on reference materials...

Elemental Chemostratigraphy of the Cottage Grove Hole MP-18 Core: Implications for Litho- and Hydrostratigraphy in Southcentral Wisconsin

Part of a larger regional study of the Eau Claire Formation, the core, from Dane County, Wisconsin, was tested using a portable x-ray fluorescence (pXRF) elemental analyzer. The report presents the data set and discusses lithologic interpretations, subsurface lithostratigraphic correlations, and hydrostratigraphic frameworks. Includes photos of the core.
